Really? Yet Another Web Framework/CMS?

YetaWF (pronounced "Yet Another Web Framework") is a new open source product, developed by Mike van der Meulen (Softel vdm, Inc.). It was used to develop and host the company's own site, the LinksWithPics service, the WEO Report service (now discontinued), this site and various other sites.

It builds on ASP.NET Core MVC to create a web framework/CMS for developers. While it has many attributes commonly found in today's CMS like DotNetNuke, Umbraco, Drupal, etc., it instead focuses on rapid application development. Tightly integrating with Visual Studio 2015/2017, it lends itself to rapid module development, offering built-in BREAD (Browse, Read, Edit, Add, Delete) module generation, taking advantage of ASP.NET, Data Annotation, Templated Helpers, UIHint and many other innovative features made possible by ASP.NET. Rather than being all things to all people, it narrowly focuses on offering 100% of the features that will satisfy most average websites and offers a platform for rapid custom development.

It has been in development since 2010, upgraded from MVC 3 to 4, 5 and now supports ASP.NET Core MVC. It has been used since then to host numerous sites. It's definitely not a beta version, but may need some extra documentation, which is in the works. With the move to ASP.NET Core all of YetaWF's features are available and other than a lot of framework code that had to be changed, all modules were ported with minimal source code changes, resulting in an immediately mature product.

YetaWF offers easy to design Single Page Sites, Static Pages and of course traditional multi-page sites, all easily created with modules that are added to pages.

YetaWF's core doesn't use a specific front-end framework, yet it's a Single Page Application by default, built using TypeScript and native JavaScript browser interfaces. All rendering is completely modular and implemented using addon packages, which could include any front-end framework. The default uses jQuery, jQuery-UI, Kendo UI and many client-side plugins (like grids, menus, syntax highlighter, lightbox, CKEditor, tabs, overlays and many more). It combines these with automatic features like JavaScript and CSS minifier and bundling, HTTP response compression (take a look at the source for this page) without burdening the developer with administrative tasks. No build pipeline to set up or maintain.

YetaWF also takes a new approach to localization by being designed from the ground up with localization in mind (again, without burdening the developer with administrative tasks). Pages, modules, down to SQL tables or file data are fully localizable. Adding/removing languages is possible at any time, not just at design-time. 

For the site administrator, it offers site management, automated backups, easy version upgrades, scheduled tasks and of course complete control over authentication and user/role authorizations. And you can even use it on your phone/tablet without downloading any apps, with full access to all administrator features.

Try our Demo Site which lets you log into YetaWF as a Superuser so you can see all the Administrator features (you can't make any changes to the site).

Latest News

YetaWF 4.0.0 Released on September 4, 2018

  • Removed all use of Razor for Views and Display/EditorTemplates reducing page load time by 15% on average. Razor is now only used for main pages, i.e., pages defined by skins. A skin typically only defines 6 pages.
  • Site restart has been reduced to (typically) around 5-10 seconds maximum for an average site, making a restart much less painful.
  • All HTML rendering of former templates (now Components), modules, pages is performed by a YetaWF package so all rendering can be replaced/changed by providing a new rendering package. The default rendering package (YetaWF_ComponentsHTML) which uses jQuery, jQuery-UI, Kendo UI can be replaced with any component framework (yes, it's not exactly trivial, but there is a well-defined interface and requirements).
  • All core JavaScript code (YetaWF_Core package) has been transitioned to TypeScript and no longer uses jQuery.
  • Localization has been reworked (and some bug fixes).
  • Import/Export and backups of packages and package data now use JSON data. This means that any backups, exported zip files, prior to 4.0.0 cannot be used with 4.0.0. The only supported way to convert to 4.0.0 is by upgrading an existing site. Backup files cannot be used.
  • New TimeOfDay template.
  • New DayTimeRange template.
  • New WeekDays template.
  • Authentication now supports forcing a new user password during login.
  • X-Frame-Options can be set using a site wide default and for each individual page, to allow/disallow site pages from being used in IFrames (by any site).
  • Many bug fixes.
